• Branch/Environment:

  • Environment: Visor SandboxJS

• Describe the bug:
  The Visor SandboxJS environment silently aborts execution when an await expression is placed inside a try-catch block. The script stops executing and returns undefined without throwing any visible errors.

• Reproduction steps:

  1. Create a Visor script with a try-catch block.
  2. Inside the try block, add an await expression (e.g., await bash(...)).
  3. Run the script.

• Actual behavior:
  The script execution silently aborts at the await expression and returns undefined.

• Expected behavior:
  The await expression should execute normally inside the try-catch block, or if there's an error, it should be caught by the catch block.

• Business Impact:

  • Blocking implementation? Yes, it causes scripts like the CVE processor to fail silently and report incorrect results (e.g., Processed: 0).
